Barcelona full-back Sergi Roberto has warned Real Madrid that the champions will fight to cut the six-point gap at the top of LaLiga.
Sergio Ramos' 90th-minute header secured a 1-1 draw for Madrid in Saturday's Clasico at Camp Nou to preserve their unbeaten league run and their advantage at the top of the table.
A Madrid win would have opened up a nine-point deficit - only Louis van Gaal's Barca in 1998-99 have won LaLiga from so far back.
Roberto felt Barca deserved to win the match but is fully confident that they will haul in Zinedine Zidane's side if they keep their commitment levels high.
